[0003] However, currently used leak detection equipment typically employs pressure testing devices, which are cumbersome to operate. Ensuring the workpiece's seal is crucial, making it difficult to visually observe leaks. Furthermore, misalignment during workpiece fixation can lead to inaccurate data and compromised leak detection efficiency. To address these issues, we offer an intelligent pressure testing and leak detection device. Utility Model Content

A support frame is provided on the water tank body, and a lifting mechanism is provided at the top of the support frame. A lifting plate is fitted on the surface of the support frame and is connected to the lifting mechanism. A placement platform is provided below the lifting plate. Connecting rods are fixedly connected to the four corners of the placement platform, and the tops of the connecting rods are fixedly connected to the bottom surface of the lifting plate. An inflation mechanism for filling the workpiece with high-pressure gas is provided on the placement platform, and the workpiece is placed on the inflation mechanism. A clamping mechanism for fixing the workpiece is provided on the lifting plate. An industrial camera is mounted on the back of the water tank body via a bracket.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] like Figures 1 to 5 As shown, this utility model provides an intelligent pressure testing and leak detection device, including a water tank body 1 and a workpiece 10. A support frame 2 is provided on the water tank body 1, and a lifting mechanism is provided at the top of the support frame 2. A lifting plate 7 is fitted on the surface of the support frame 2, and the lifting plate 7 is connected to the lifting mechanism. The lifting mechanism can drive the lifting plate 7 to rise and fall on the surface of the support frame 2. A placement platform 12 is provided below the lifting plate 7. Connecting rods 9 are fixed to the four corners of the placement platform 12, and the top of the connecting rods 9 is fixed to the bottom surface of the lifting plate 7. When the placement platform 12 moves with the lifting plate 7, it will drive the workpiece 10 on the placement platform 12 to rise and fall inside the water tank body 1, so as to facilitate the picking and placing of the workpiece 10. An inflation mechanism for filling high-pressure gas into the workpiece 10 is provided on the placement platform 12, and the workpiece 10 is placed on the inflation mechanism. A clamping mechanism for fixing the workpiece 10 is provided on the lifting plate 7. The clamping mechanism can... This ensures that the workpiece 10 is securely fixed on the placement platform 12, which is beneficial for subsequent pressure testing and leak detection. An industrial camera 11 is mounted on the back of the water tank body 1 via a bracket. With the above structure, after the workpiece 10 is placed on the inflation mechanism on the placement platform 12, the lifting mechanism can be activated to lower the lifting plate 7 and the placement platform 12 into the water tank body 1, so that the workpiece 10 is completely submerged in water. Then, compressed gas is injected into the inflation mechanism and enters the workpiece 10. After the water surface is slightly calm, the industrial camera 11 is used to observe whether there are bubbles on the water surface and make an evaluation result. Finally, the lifting mechanism is used to rise, so that the inflation mechanism depressurizes the workpiece 10. After the depressurization is completed, the clamping mechanism is released, and the workpiece 10 is removed to complete the test. The machinery, parts and equipment in this device all adopt conventional models in the existing technology, and the circuit connection adopts conventional connection methods in the existing technology, which will not be described in detail here.
[0021] like Figures 1 to 3 As shown, the lifting mechanism includes a top plate 3 and a protective box 6. The top plate 3 is fixed to the top of the support frame 2, and the protective box 6 is fixed to the lifting plate 7. A lifting cylinder 4 is installed on the top plate 3. The telescopic end of the lifting cylinder 4 is connected to the protective box 6. With the above structure, the lifting cylinder 4 can be used to drive the protective box 6 and the lifting plate 7 to rise and fall on the surface of the support frame 2, thereby realizing the lifting and falling of the workpiece 10 on the placement platform 12 within the water tank body 1, which facilitates the picking and placing of the workpiece 10.
[0022] like Figures 2 to 4 As shown, the clamping mechanism includes a clamping cylinder 8 mounted on the lifting plate 7, and the clamping cylinder 8 is located inside the protective box 6. The telescopic end of the clamping cylinder 8 contacts the top of the workpiece 10. With the clamping cylinder 8 in place, when the workpiece 10 is placed on the inflation mechanism, the telescopic end can be squeezed against the top of the workpiece 10 by the operation of the clamping cylinder 8, thereby ensuring the sealing between the workpiece 10 and the inflation mechanism, and also ensuring the accuracy of the leak detection of the workpiece 10.
[0023] like Figures 1 to 3 As shown, two balancing cylinders 5 are installed on the top plate 3, and the lifting cylinder 4 is located between the two balancing cylinders 5. The extension and retraction ends of the two balancing cylinders 5 are fixed to the protective box 6. With the setting of the two balancing cylinders 5, the lifting stability of the protective box 6 and the lifting plate 7 under the operation of the lifting cylinder 4 is ensured, and the protective box 6 and the lifting plate 7 are kept stationary at any position within the stroke range.
[0024] like Figure 4 and Figure 5 As shown, the inflation mechanism includes an inflation seat 13 fixed to the placement platform 12. A sealing ring 15 is fixed to the inflation seat 13. An inflation hole 14 is opened on the surface of the inflation seat 13 and extends to the middle of the inflation seat 13. With the above structure, when the workpiece 10 is placed on the inflation seat 13, the sealing ring 15 will seal the bottom surface of the workpiece 10, and the workpiece 10 will be squeezed downward by the clamping cylinder 8 to ensure the sealing between the workpiece 10 and the inflation seat 13. After the workpiece 10 is sealed, it will be lowered into the water tank body 1 along with the placement platform 12 and completely submerged in water. High-pressure gas will then be injected into the workpiece 10 through the inflation hole 14 to facilitate subsequent observation of the water surface.
[0025] like Figures 1 to 3 As shown, there are two support frames 2. The bottom ends of the two support frames 2 are fixed to the inner bottom wall of the water tank body 1. The overall stability of the device is ensured by the setting of the two support frames 2, making the lifting plate 7 more stable when lifting and lowering, and also ensuring the fixation of the workpiece 10 on the placement platform 12.
[0026] The working principle and usage process of this utility model are as follows: First, the workpiece 10 is placed on the inflation seat 13. Then, the workpiece 10 is pressed and fixed on the inflation seat 13 by the operation of the clamping cylinder 8 to ensure the sealing between the workpiece 10 and the inflation seat 13. Then, the lifting cylinder 4 controls the lifting plate 7 and the placement platform 12 to descend into the water tank body 1, so that the workpiece 10 is completely submerged in water. Next, compressed gas is injected into the workpiece 10 through the inflation hole 14. After the water surface is slightly calm, the industrial camera 11 is used to observe whether there are bubbles on the water surface and make an evaluation result. Finally, the lifting mechanism is used to rise, so that the inflation mechanism depressurizes the workpiece 10. After the depressurization is completed, the clamping mechanism is released, and the workpiece 10 is removed to complete the test. The operation is more convenient and effectively improves the efficiency of pressure testing and leak detection of the workpiece 10.
